HP Data Protector: Cannot load exchanger medium (Target drive is busy.)

vSphere 5.1: The new Web-Client

Without a doubt one of the biggest changes  with the new vSphere 5.1 release is the changeover to the web-client. Even if the “old” Windows-client still exists, the web-client is now seen as the new main-interface. Last year VMware released the first version of the web-client together with vSphere 5.0. In this version it wasn´t […]

vSphere 5.1: Getting started with vSphere Replication 5.1

With the release of vSphere 5.1 today VMware integrated vSphere Replication into the basic product, without the need of buying any separate license.
